I got this for my bedroom to help most heat but I also have some allergies. I absolutely love this! It heats, cools and purifies. And boy does it heat really good! My room is quite large with double doors into a bathroom and it will heat the whole space. It rotates and you can purify as you cool your room. Also it comes with a handy little remote so you don't have to get up if you are across the room. 
Honestly it a the best one I have ever gotten! I would highly recommend!
